i IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 136,825, dated March1S, 1873.

To all whom it may concern.- r

y Be it known that I, OLIVER B. EVANS, of

Titusville, Crawford county, Pennsylvania,-

have invented certainImprovements in Steam- Boilers for LaundryPurposes, of which the following is a specification:

My invention relates to an improvementin A a steam-boiler for laundrypurposes, drawing of which I herewith furnish with the following to thecylinder a. Fig. 4, letters E E, arewings to be placed on the inside ofboiler F. Fig. 5 is the reversed end of cylinder a. Fig. 6 is the bottomof cover S. Fig. 7 Sis boiler F and cylinder a combined. Fig. 8, letterso c, are posts on which I rest the journals D D.

I combine my invention with boiler F by placing cylinder a with anopening on one side to receive the clothes, and inclose the same by themovable cover G, which cylinder I turn with crank b soas to displace theclothes, that all parts may receive the steam equally, and also an equalamount of friction from the `corrugated sides of 'the cylinder a. I holdthe cylinder in place by resting the journals D D at each end on the topof two posts, c c, placed and fastened on the inside of boiler F, withaange or cap on the journal D to prevent a lateral movement. The jourinkeeping the steam equal on all sides of the cylinder; also to serve asconductors to return the condensed steam to the bottom of the boiler F.The cover S I construct with a concave top, into which I place coldwater to condense` the steam that arises above the cylinder a. I allowthe sides ofthe cover S to pass over the outside of the boiler F andfasten with a catch, which is attached to the end of the boiler.`

This arrangement is to prevent the cover from rising by the pressure ofthe steam.

I add liquid ammonia and chlorine to the water in the boiler F to assistin bleaching.A

What l claim, and desire to secure by Letters Patent, is

The boiler F and recessed lid S, in combination with the corrugated andperforated cylinder a and wings E, all arranged as and for the purposesspecilied. OLIVER B. EVANS.
